Question #26296

An angle is considered acute if it is less than 90 degrees, obtuse if it is greater than 90 degrees, and a right angle if it is equal to 90 degrees. Using this information, write a C++ program that accepts an angle, in degrees, and displays the type of angle corresponding to the degrees entered.
A student’s letter grade is calculated according to the following schedule:
Numerical grade Letter grade
Greater than or equal to 90 A
Less than 90 but greater than or equal to 80 B
Less than 80 but greater than or equal to 70 C
Less than 70 but greater than or equal to 60 D
Less than 60 F
Using this information, write a C++ program that accepts a student’s numerical grade, converts the numerical grade to an equivalent letter grade, and displays the letter grade.

Expert's answer

#include <iostream>

using namespace std;

int main()

{

/* Ask the user to enter an angle in degrees */

double angle;

cout << "Enter an angle in degrees: ";

cin >> angle;

/* Normalize the angle if it's bigger than 360 degrees */

while (angle > 360)

angle -= 360;

/* Print the type of the angle */

if (angle == 90)

cout << "The angle is right." << endl;

else if (angle < 90)

cout << "The angle is acute." << endl;

else

cout << "The angle is obtuse." << endl;

return 0;

}

using namespace std;

int main()

{

/* Ask the user to enter an angle in degrees */

double angle;

cout << "Enter an angle in degrees: ";

cin >> angle;

/* Normalize the angle if it's bigger than 360 degrees */

while (angle > 360)

angle -= 360;

/* Print the type of the angle */

if (angle == 90)

cout << "The angle is right." << endl;

else if (angle < 90)

cout << "The angle is acute." << endl;

else

cout << "The angle is obtuse." << endl;

return 0;

}
